But she revealed on Wednesday that when Destiny's Child were at the height of their fame, all she felt was depression.
'I was suicidal … and wanted out,' she confessed during an appearance on The Talk on Wednesday.
Williams, 37, said she had started suffering from depression when she was 13 and it lingered throughout her late teens and 20s even as she, Kelly Rowland and Beyonce Knowles hit the big time.
Her depression worsened, though, to the point where she thought about killing herself.
It wasn't until her 30s, she said, that she learned that what she was feeling had a name and a clinical diagnosis.
After her interview aired on the CBS daytime chat show, Williams tweeted: Thank you @TheTalkCBS for being a safe place to talk about #depression #mentalhealthawareness!! Don’t be afraid to reach out for help!'
